How old are your ears?
Your ability to hear very high frequencies fades with age — so the highest tone you can still hear hints at your "hearing age." Press start, answer yes or no as the pitch drops from 20 kHz, and get your bracket in about a minute. Use wired headphones and turn the volume up a little; it runs entirely in your browser.
Before you start
- Wired headphones, not BluetoothThis test lives at the very top of the frequency range — exactly where Bluetooth codecs and tiny speakers roll off. Wired headphones are the only way to get a fair reading.
- Turn it up a littleVery high tones already sound quiet, so a too-low volume hides tones you could otherwise hear. Nudge it up — but never to the maximum.
- Go somewhere quietBackground hiss masks faint high tones. A quiet room gives your ears their best shot at the upper frequencies.
- Only count what you really hearHigh-frequency tones are faint and easy to imagine. Tap "yes" only for a tone you genuinely perceive, or your hearing age will read younger than it is.
How the hearing age test works
- 1Press start. The test plays a tone at 20 kHz — the very top of human hearing — then steps the pitch down: 19, 18, 17 kHz and so on.
- 2Answer yes or no. For each tone, tap Yes if you hear it or No if it's silent (or press Y / N). Because pitches descend, the first tone you hear is the highest you can hear.
- 3Get your bracket. The highest tone you caught maps to a hearing-age range and a spot on the frequency scale — from teenage ears near 20 kHz down to 60-plus around 8 kHz.
- 4Go deeper. Want a per-ear picture across the whole speech range, not just the top? Run the full hearing test, or play any exact pitch with the tone generator.
Why the highest tone you hear reveals your age
Hearing relies on thousands of tiny hair cells in the cochlea, each tuned to a frequency. The cells tuned to the highest frequencies sit at the very entrance of the cochlea and take the most wear, so they're the first to go — from a lifetime of sound, from loud exposure, and simply from ageing. This is presbycusis, and it's near-universal: a teenager can often hear up to 18–20 kHz, but that ceiling drops by roughly 1–2 kHz per decade for most people.
That steady, predictable decline is what lets a single number — the highest tone you can hear — estimate a "hearing age." It's a fun heuristic, not a medical measurement: the mapping is a population average, and your own gear, volume, and room all shift it. The famous "mosquito tone" around 17 kHz works on exactly this principle — it was used as a ringtone teenagers could hear but many teachers couldn't, and later (controversially) as a deterrent to make young people move along.
Typical highest audible frequency by age
A rough population guide — individuals vary widely, and noise exposure can age ears faster than the calendar. Use it to sanity-check your result, not as a verdict.
| Age range | Typical ceiling | What it sounds like |
|---|---|---|
| Under 18 | 18–20 kHz | The full top end — mosquito tones, the highest cymbal shimmer. |
| 20s | 16–18 kHz | Most of the top intact; the very highest tones start slipping. |
| 30s | 15–16 kHz | The mosquito ringtone gets hard to hear. |
| 40s | 13–15 kHz | High cymbals and "air" in music soften noticeably. |
| 50s | 11–13 kHz | Upper harmonics of voices and instruments dim. |
| 60s | 9–11 kHz | Consonants like "s" and "th" get harder in noise. |
| 70-plus | 8 kHz or below | Speech clarity in crowds is the everyday challenge. |
Noise-induced hearing loss stacks on top of ageing: concerts, power tools, and loud earbuds all take their heaviest toll at 3–6 kHz first, then spread. Protect the ears you have — the damage doesn't grow back.
Hearing age glossary
- Presbycusis
- Age-related hearing loss. It starts at the highest frequencies and works downward, which is what makes a "hearing age" estimate possible.
- Hair cells
- Sensory cells in the cochlea that convert sound into nerve signals. The ones tuned to high frequencies wear out first and don't regenerate in humans.
- Mosquito tone
- A high tone around 17 kHz that most young people hear easily but many older adults can't — used as a ringtone and, controversially, as a deterrent.
- Frequency
- Pitch, measured in hertz (Hz). 8 kHz is a shrill whistle; 20 kHz is at the edge of human hearing.
- Sample rate
- How many audio samples per second your device outputs. A 44.1 kHz rate can only reproduce tones up to ~22 kHz, which caps this test at the top.
- Codec roll-off
- The way Bluetooth audio codecs quietly discard the highest frequencies to save bandwidth — often above 15–17 kHz — which can fake a poor result.
Hearing age test FAQ
Is losing 15 kHz+ hearing normal at 30?
Completely normal. High-frequency hearing declines steadily from your late teens onward, and by 30 a ceiling around 15–16 kHz is typical. You almost never use those top frequencies in daily life — speech lives mostly between 250 Hz and 6 kHz — so losing the extreme top has little practical effect. The "hearing age" number is a fun snapshot of that natural decline, not a warning sign on its own.
Why can my kid hear the mosquito tone and I can't?
Because the roughly 17 kHz "mosquito" tone sits right in the band that fades first with age. Children and teenagers still have healthy high-frequency hair cells and hear it easily, while those same cells have worn down in most adults over 25 or so. It's the exact effect this test measures — and the reason the tone was once used as a ringtone students could hear but teachers couldn't.
Can headphones or earbuds cause a bad result?
Yes, very often — the gear is the number-one reason for a misleadingly low score. Bluetooth codecs typically roll off above 15–17 kHz, and small or cheap drivers struggle to reproduce the top octave at all, so tones you could actually hear never make it to your ears. Always use wired headphones for this test. If your result jumps when you switch from Bluetooth to wired, the headphones were the limit, not your ears.
Why do I get different results on different headphones?
Because every set of headphones has a different high-frequency response and every device a different maximum volume. One pair might reproduce 18 kHz cleanly while another rolls off at 15 kHz; one phone might drive them louder than another. The test measures the whole chain — your ears plus your gear — so changing the gear changes the ceiling. For the fairest read, use good wired headphones at a steady, moderate volume.
Does volume change my hearing age result?
It can. A very high tone that's inaudible at low volume becomes audible when you turn it up, so cranking the volume can push your apparent ceiling higher than it really is. Keep the volume moderate and consistent, and don't raise it tone by tone chasing a younger number. The point is a fair snapshot, not the best possible score.
Is this hearing age test medically accurate?
No — treat it as entertainment with a grain of science. The age mapping is a population average, and your headphones, volume, room noise, and sample rate all shift the result. It's a genuinely fun way to see the natural high-frequency decline everyone experiences, but it is not a diagnosis. For an actual per-ear measurement, run the full hearing test, and for any real concern, see an audiologist.
What's the highest frequency a human can hear?
The textbook range for human hearing is about 20 Hz to 20 kHz, but that 20 kHz ceiling really only applies to young children in ideal conditions. Most healthy young adults top out around 17–19 kHz, and the ceiling drops with age. There's also a hard technical limit: a standard 44.1 kHz audio device can't reproduce anything above ~22 kHz, so 20 kHz is effectively the top of what this test can even play.
Can I improve or reverse my hearing age?
You can't regrow the high-frequency hair cells you've lost — human cochlear cells don't regenerate — so the age-related part is permanent. What you can do is stop it getting worse: keep listening volumes moderate, use hearing protection at concerts and around power tools, and give your ears quiet recovery time after loud exposure. Protecting what you have is the whole game; the damage from noise is cumulative and avoidable.
